The new model P200 Hydra-Cell metering solutions pumps from this company feature new gearbox reducers with ratios from 60:1 to 5:1. They are designed for a range of processing applications and for use in manufacturing facilities. Combined with Variable Frequency Drive (VFD) electronic flow adjustment, Model P200 metering pumps with new gearboxes reportedly provide accurate flow throughout the turndown range at up to 81.0 gph (255.4 lph) at pressure ratings to 350 psi (24 bar) for non-metallic pump heads, and 1000 psi (69 bar) for metallic pump heads. The separate gearboxes can also allow for versatility in changing applications and to prevent cross-contamination of actuating hydraulic oil.
The pumps feature a multiple-diaphragm design that reportedly minimizes pulsations, producing smooth, linear flow without the need for expensive pulsation dampeners. A replenishment valve in every piston assembly may ensure even actuating oil on every stroke for continuous accuracy. The seal-less design of Hydra-Cell means that there are no seals, cups, or packing to leak, wear, or replace. Spring-loaded, horizontal disk check valves and the seal-less design enable the P200 to handle viscous fluids and abrasive particulates up to 200 microns in size.
